My invention relates to `bag lling devices and more particularly todevices for iilling packages with material in uniform quanti-i ties;andthemobjectis to provide fillingV de- 5 vices which are simpleinconstruction Vand highly v eicient in operation vand which will feedmaterial. in uniform quantities and which can bemanufactured andinstalled at small cost and whichv are economical be-.V

cause the packages orbags can `be filled Awith rapidity and' 'accuracywithout waste and which are easily operated.` The filling devices are,useful in handling such vmaterial as mixed animal and poultry food andother material of similan character. Other objects and advantagesfwillbe fullyexplained inthe fol1owing`description and the invention will bemore particularly' pointed out in the claims.

The support 11- is prevented 'from'rotating by-a key32 y,which is mounted in ar verticalslot 1n the guide ll. lf lhelcollarl yis'made nonrotatable bya screw 33which is projected throughthe collar l5i'ntothe key 33." lA, screw' may also be projected throughthe collar l5' and the .Supportl as shown in Figs. 2, 3,and 4. y Thesupport 1l is moved vertically-by a nut 34 which isfor convenienceprovided -with handles for turning the" screw. 'if-he bag supportingplatform lOismaderigid l`with the support ll by a iiangedcollar 35 whichis bolted to the platform `l0.` The collar 35 is screwed on the support1l'. The platform l0 can'be elevated by turningthe .screw V34 andloweredl byturning the screw 34 in the opposite direction. The platformlO has al cut-0111336 for mounting the bags ontheholders 8 andforremoving the/bagsI when filled;` The platformjlO can bebrofught closertoor furtherfrom the bag-carriersS.; The devicesS carry-the'bagsand alsoserve gs means fordirecting thefmaterialintothel Means larefprovidfedfor feedingfmater-iai into'the machine.4 A pipe 85fleads froma supplysource into aA distributinghoppen 2` which is stationarily mounted. This-hopper has-`openings4 in the bottom for es eape'o'f the foodmaterial.'y A conesshaped dividery directs Vthe material y'to theopenings 4L'.K4 Arms 36are` attached to the hopper 2 andf'supported ontherod' which is stationary., 'Ifhe'shaft 6` isv 'stationary and' a iball bearing' race 37; one part being rigid Withthe-shaftiandthe -otherpart rigid with the carrier- 9: Tlie carrier 9.V An arm 23 is rigidwitha sleeve 16 lwhich surrounds therod v38.5 The vsleeve 16I is providedwith ball bearings. 39. flanged .ring|` 39 vis attached to thecarrier 9.Lugs 26 are mounted on the body, of the ring 39. `A dog 24 ispivotallyconnected tothe arm 23.and.this dog is provided with *hooksy 25 whichare adapted to engage the "lugs 26 for actuating :or rotatingy thecarrier 9.' A bell crank lever 18is fulcrumed on the platform 30 bymeans of a bearing 19. This lever 18 is pivotally connected to a linkbar 2O Which is pivotally connected to a crank 17 Which is rigid withthe sleeve 16. The pivotal connection of 17 and 20 permit horizontalswinging motion. A spring 40 causes the dog 24 to bear against theperiphery of the carrier 9. The effect of this is to make the dog 24engage the lugs 26. A pressure of the foot on lever 18 Will rotate thesleeve 16 by means of link bar 20 and lever 17. When the pressure of thefoot is removed the dog 24 Will be pushed along on the periphery of thecarrier 9 by the spring 22 and arm 23, so that the dog (by means ofhook' 25) Will engage a lug 26. The dog 24 and. arm 23 Will be broughtto the dotted outlineposition shown in Fig. 5. The dog 24 will slide onthe periphery of the carrier 9. Pressure is put on the lever 18 to moveor rotate the carrier 9 and all the bags one-quarter turn. At the end ofthe quarter turn the carrier 91Will be locked stationary. The flange41has notches 42 in its periphery. An arm 43 is rigid with sleeve orshaft 16 and this arm has a hook 44 which catches in a notch .42.' Inthis manner the carrier 9 is held stationary temporarily. When pres-Sure is relieved from the vlever 18, varm 43 Will be brought by thespring 22 to dotted outline position.

j In operation, the bags are clamped on the holders 8 (by clamps 45 .ifnecessary). The bags are telescoped on the holders and the bottoms ofthe-bags rest on the platform 10 and slide around thereon. Each bag Willbe part-lyiilled When the bag registers with the first opening 4 in feedplate 3, then fur-f ther filled as the bag registers With the nextopening 4. Then if the bag is not filled by this time, it will becompletely filled when it registers With the third opening 4. The

Y bagthen ismoved on to be removed. through the cut-out 36. The carrierplate 9 is easily moved manually by reason of the ball bearings 37.Butthe carrier is positively moved by the lever 18 and the dog 24 Withtheir connections. After each rotation a quarter turn by the lever 18,shaft 16, and arm 23, the dog 24is brought back lto dotted outlineposition automatically by the spring 22` pulling on arm 23.. v

5. A bag filling apparatus comprising a hopper provided with a basehaving feed openings, a bag supporting platform, means for verticaladjustment of said platform, a rotating bag carrier provided Withtubular bag supports and provided with openings adapted to register withthe openings of said hopper base and to discharge material throughsaidtubular supports, said carrier rotating in close proximity to saidhopper base, means for positioning said carrier to cause the openingstherein to register With the openings in said hopper base step by step,and means for automatically bringing said positioning means back tostarting position after each step movement.

6. A bag lling apparatus comprising a hopperprovided Withy a base havingfeed openings, a bag carrier rotating in close proximity to said hopperbottom and provided with openings adapted to register With said hopperbottom openings, tubular bag supports attached to said carrier aboutsaid openingsfor receiving material therefrom, a bag supporting platformand means for vertically adjusting said platform relative to saidtubular supports, means for positioning said carrier relative to saidhopper bottom to cause the carrier openings to register With the hopperbottom openings in succession, and means for locking said carriertemporarily stationary at each step movement.

In testimony whereof, I set my hand, this 20th day of September, 1929.
